将 getStaticProps 与 next-redux-wrapper 一起使用 [英] Using getStaticProps with next-redux-wrapper

问题描述

我正在开发一个简单的 next.js 应用程序.对于状态管理，我使用的是 next-redux-wrapper.在我的主页中，我想使用 store.dispatch 从我的 api 获取数据库中的所有房间.

I'm developing a simple next.js app. For state management I'm using next-redux-wrapper. In my home page I want to fetch all the rooms in my database from my api using store.dispatch.

当我使用 getServerSideProps 并调度它起作用的操作时，它会获取我所有的房间.但问题是当我想用 getStaticProps 获取房间时它不起作用，什么也没发生.

When I use getServerSideProps and dispatch an action it works, it fetches all my rooms. But the problem is when I want to fetch rooms with getStaticProps it doesn't work nothing's happening.

我应该在开发大型应用程序时使用 next-redux-wrapper 还是应该尝试其他库.因为我想在我的应用程序中使用 getStaticPaths、getStaticProps 和 getServerSideProps.在这些函数中，我通常会调度一个 redux 操作.

Should I use next-redux-wrapper when I develop big apps or should I try other libraries. Because I want to use getStaticPaths, getStaticProps and getServerSideProps in my app. And in theese functions I'm usually gonna dispatch an redux action.

Store.js 文件

Store.js File

import { createStore, applyMiddleware } from "redux";
import { HYDRATE, createWrapper } from "next-redux-wrapper";
import thunkMiddleware from "redux-thunk";
import reducers from "./reducers/reducers";

const bindMiddleware = (middleware) => {
 if (process.env.NODE_ENV !== "production") {
 const { composeWithDevTools } = require("redux-devtools-extension");
 return composeWithDevTools(applyMiddleware(...middleware));
 }
 return applyMiddleware(...middleware);
};

const reducer = (state, action) => {
 if (action.type === HYDRATE) {
 const nextState = {
 ...state,
 ...action.payload,
 };
 return nextState;
 } else {
 return reducers(state, action);
 }
};

const initStore = () => {
 return createStore(reducer, bindMiddleware([thunkMiddleware]));
};

export const wrapper = createWrapper(initStore);

_app.js 文件

import "../styles/globals.css";
import { wrapper } from "../redux/store";

function MyApp({ Component, pageProps }) {
  return <Component {...pageProps} />;
}

export default wrapper.withRedux(MyApp);

pages/index.js 文件

pages/index.js file

import Layout from "../components/layout/Layout";
import Home from "../components/Home";
import { getRooms } from "../redux/actions/roomActions";
import { wrapper } from "../redux/store";

function HomePage() {
 return (
 <Layout>
 <Home />
 </Layout>
  );
}


//THIS WORKS
/*export const getServerSideProps = wrapper.getServerSideProps(
  (store) =>
    async ({ req }) => {
      await store.dispatch(getRooms(req));
    }
);*/
// THIS WORKS


// THIS DOES NOT WORK
export const getStaticProps = wrapper.getStaticProps(({ store }) => {
 async () => {
 await store.dispatch(getRooms("http://localhost:3000/"));
 };
});
// THIS DOES NOT WORK

export default HomePage;

推荐答案

使用7.0.x版本.npm install next-redux-wrapper，默认安装6.0.x

Use the 7.0.x version. npm install next-redux-wrapper, installs the 6.0.x by default

而且只有 7 及以上版本的 next-redux-wrapper 支持此功能

And this is supported only in 7 and above version of next-redux-wrapper
